Immunologic, virologic and drug resistance outcomes in an HIV-infected prospective cohort on treatment in South Africa.

In September 2016, South Africa introduced the universal test and treat (UTT) programme to manage HIV infection. However, the development of drug resistance and sustaining viral suppression are challenges to the success of treatment programmes. This prospective observational study describes virologic, immunologic, and drug resistance profiles in a test and treat cohort in north-eastern South Africa.
